Using the Board Update Portal to Write User Designs
The Board Update Portal allows you to write new designs to the user hardware 1
portion of flash memory. Designs must be in the Nios II Flash Programmer File
(.flash) format. However, if you have generated a SRAM Object File (.sof) that
operates without a software design file, you can still use the Board Update Portal to
upload your design. In this case, leave the Software File Name field blank.

Design files available from th
page include
.flash
files. You can also create .flash files from your own custom design. Refer to
“Preparing Design Files for Flash Programming” on page A–2
for information about
preparing your own design for upload.
To upload a design over the network into the user portion of flash memory on your
board, do the following:
1. Perform the steps in
“Connecting to the Board Update Portal Web Page” on
to access the Board Update Portal web page.
2. In the Hardware File Name field, specify the .flash file that you either
downloaded from the Altera website or created on your own. If there is a software
component to the design, specify it in the same manner using the Software File
Name
field. Otherwise, leave the Software File Name field blank.
3. Click Upload and then wait for the files to write to flash memory. A progress bar
indicates the percent complete.
4. To configure the FPGA with the new design, set the SW4.3 DIP switch to the FACT
OFF (logic 1) position and power cycle the board.

As long as you don’t overwrite the factory image in the flash memory device, you can
continue to use the Board Update Portal to write new designs to the user hardware 1
portion of flash memory. If you do overwrite the factory image, you can restore it by
following the instructions in
“Restoring the Flash Device to the Factory Settings” on
